    If the numbers 1 to 5 are written out in words: one, two, three, four, 
    five, then there are 3 + 3 + 5 + 4 + 4 = 19 letters used in total.

    If all the numbers from 1 to 1000 (one thousand) inclusive were written 
    out in words, how many letters would be used?

    NOTE: Do not count spaces or hyphens. For example, 
    342 (three hundred and forty-two) contains 23 letters and 
    115 (one hundred and fifteen) contains 20 letters. The use of "and" 
    when writing out numbers is in compliance with British usage.
